Benefits of technology

[0005]The present invention consists of a dismountable and mobile system at the same place where the mining activities are performed, preventing the hoppers from being moved to other locations where the required maintenance and repair are performed. The system allows the hopper to be raised from the ground and to be rotated at 360°, with substantial costs savings since hiring cranes being able to reach the location to turn the hopper is not required. On the other hand, it also brings operational time savings since operations often cannot start until the arrival of the crane and mooring and securing the hopper adequately for its raising and overturning and fastening is also time-consuming. In addition, the fastening elements between the towers allow a fast and secure fastening requiring no supports between the ground and the hopper.

Embodiment Construction

[0012]The apparatus intended to raise and turn mining hoppers is comprised of a dismountable, structural, dismountable, pyramid-shaped tower A (1) and a tower B (2) having mobile elements at both towers (1,2) which allow to raise the hopper off the ground (5) up to a specified height and rotate it to a position allowing easy access to the areas or elements to be maintained or repaired. The overturning apparatus joins the hopper by using attachable mechanical fastening means (3,4) made up of a first part (3) that is fixed on the hopper and a second part (4) that is in each one of the towers and rotates, said fastening means being of an attachable and mechanical kind (3,4) for example, Plates or Flanges, the hopper (5) getting joined to the towers (1,2) on both sides, which allows raising thereof. The first part (3) of the attachable mechanical fastening means (3,4) is preferably located as close as to the point equivalent to the center of gravity of the hopper as possible. During the...

Abstract

A pyramid-shaped tower apparatus is described that will raise and turn mining hoppers for easy access to the areas or elements that need to be maintained or repaired.

Description

FIELD OF APPLICATION OF THE INVENTION[0001]The present invention relates to the field of maintenance and repair of mining equipment, specifically in the field of repair of mining dump-trucks.PRIOR STATE OF THE ART[0002]In on-site repairing and maintaining mining equipment hoppers, the use of high tonnage cranes to lift, rotate or turn said hoppers during welding work or while replacing elements in different parts of the hopper, is presently required. This makes site maintenance of this kind of hoppers slow and expensive as it involves hiring cranes, the time of arrival of the crane to the site and the subsequent time spent in securing cables and cable slings or engaging elements in the hopper for lifting, rotating or overturning thereof, in addition to the risks of poor mooring that could cause accidents and material losses.[0003]There are in the state of the art patent applications such as Chilean applications numbers 2430-2003, 1876-2007, 2637-2008, and 2638-2008, which address th...
